Recent research has been done in regards to optically imaging using metamaterials. One such project is the hyperlens, which aims to overcome the classical diffraction limit and project a magnified image into the far field. The potential applications for this device range from nanolithography to bioimaging.
The Hyperlens Design Solver tool is intended to be used in conjunction with the Hyperlens Layer Designer tool to aid in the design and simulation of a hyperlens. The Hyperlens Design Solver tool allows users to upload designs created with the Hyperlens Layer Designer tool, make a new design, or select from several pre-existing designs. The tool then simulates the performance of the design and outputs several plots of the resulting field intensities. By using these two tools, users can experiment with different designs and evaluate performance to find the optimal design before beginning fabrication.
PhotonicsDB: Optical Constants uses the initial experimental data to interpolate the dielectric function or the index of refraction of bulk materials. Interpolations are possible only within a certain range of wavelengths taken from the initial experimental data sets.
The tool also gives the approximate data and the approximation coefficients obtained from best-fit Drude-Lorentz models for gold and silver. Depending on the number of Lorentz kernels (from 1 to 5) the Drude-Lorentz models support different accuracy of the best-fit approximation.
The imaginary part (and sometimes, the real part) of their dielectric functions can be very different depending on the source of published data. Therefore, in addition to the cubic spline interpolation of the raw experimental data, gold and silver can be interpolated using the corresponding Drude-Lorentz best-fit models. The constants of each model and the initial data set are shown in the reference window of the user interface (UI).
